Cargo Features

[dependencies]
i_overlay = { version = "1.9.3", default-features = false, features = ["allow_multithreading", "glam"] }
default = allow_multithreading

The allow_multithreading feature is set by default whenever i_overlay is added without default-features = false somewhere in the dependency tree.

allow_multithreading default = rayon
glam

Enables glam of i_float

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
